INTRODUCTION
In a very basic form a network is essentially, two or more computers connected together by some form of transmission medium
that enables them to share information. A network regardless of the size i.e. the number of computers and peripherals involved
or the area over which it is spread, works on the same essential concepts of Networking.
ADVANTAGES:-
Productivity and efficiency may be increased because of large scale, low cost production runs
Technology transfer and the accuracy of information are facilitated.
Resources are conserved as only one item of equipment is needed where before many might have been required
The worldwide exchange of information is increased
Allows access to remote computers
DISADVANTAGES:-
User work dependent upon network & data loss.
Resources could be located too far from users.
Network management and security can become very difficult.
PEER -TO-PEER NETWORK
This network does not have any centralized control by anyone and also doesn’t consist of a main frame server. What this means
is that if one user has a file or several files on a computer then it is up to the discretion of that user whether he/she would like to
allow access to that specific file or not and also decide as to what rights the accessing user may have to that file i.e. read only,
read- write or no access. The only similarity to a client server network is the fact that the physical hardware e.g. cabling,
switches along with protocols used are the same. The use of a NOS is not mandatory in this kind of set up as well.
ADVANTAGES
More resilient to disruptions i.e. if a server crashes the whole network will crash however in a P2P if a host crashes that
won’t disengage the entire network, only some transmission of data will be affected.
It is not expensive to install as servers cost a lot of money so the data processing power and storage space of individual
client machines can be fully utilized without incurring massive expenses.
Shared files can be directly accessed amongst each other, henceforth no separate storage space / equipment is
necessary.
DISADVANTAGES
P2P network can only function effectively to a maximum of 15 machines.
Security/ integrity of data can be very heavily compromised as owners/authors of files may choose not to have any
security / passwords set up for authorising use of data prior to access.
If a system resource such as a printer is connected to a client machine then on a busy day it could take up all of the
systems resources forcing it to function ineffectively / crash.

CLIENT SERVER BASED NETWORKS
In a client server based network there are many less powerful client machines that are connected to a very powerful main frame
server. Depending on the layout of the network and the environment tin which the network is built the processing for many of
the applications on the network may be conducted by the server or it may be used for various other purposes such as for
storage purposes or an internet server etc. Any communications that take place on this type of network goes through the
server. This enable very close monitoring of what happens over the network and makes administration very easy such as
assigning rights to different users depending on their relevance is one of the many advantages of a client server based network.
ADVANTAGES
Centralized - Resources and data security are controlled through the server.
Scalability - Any or all elements can be replaced individually as needs increase.
Flexibility - New technology can be easily integrated into system.
Accessibility - Server can be accessed remotely and across multiple platforms.
Speed: - Network will run far better as data and resources are handled by a dedicated machine.
Backup as all data is stored centrally it is easy to backup
Support and management as the server controls the majority of settings on the network etc the job of support is far
easier as the main element of support is provided to the server and not individual machines
DISADVANTAGES
Dependability - when the server goes down, operations cease
Lack of mature tools - it is a relatively new technology and needed tools are lacking e.g. Automate
